K2Dialed Fit System™: The K2Dialed™ Fit System creates a custom-fitting helmet no matter what your head shape is. An ergonomically inspired three-point adjustable interface maximizes fit and customization with the twist of a dial. This allows for the ultimate convenience of being able to make fit adjustments on the fly.

Full-Wrap Liner: A comfortable, washable, full-coverage, and breathable liner design wicks moisture to prevent overheating and seamlessly integrates K2's fit and audio systems.

K2 Level 3 Baseline Audio: The K2 Level 3 Baseline Audio system seamlessly connects you with your cell phone or media player. The audio system comes pre-installed in Baseline Audio Earpads. The speaker housing creates a minimal, low-profile stowage so you won't notice the speakers unless the music is playing. If you would rather ride without the speakers installed, they can be easily removed from the earpads with a detachable cord and an all-new on-cord audio controller for initiating the on-the-go pause/play and answer/hang-up functions, your media device is literally at your fingertips
